Specification of Letters Patent.

Patented Oct. 17, 1905.

Application filed July 23, 1904. Serial No. 217,782.

T0 all whom, t may concern:

Be it known that we, HENRY J. ROBINSON and THOMAS V. CONWAY, citizens ofthe United States, and residents of Cleveland, county of Cuyahoga, andState of Ohio, have invented a new and useful Improvement inPipe-Hangers, of which the following is a specification, the principleof the invention being herein eX- plained and the best mode in which wehave contemplated applying that principle so as to distinguish it fromother inventions.

Our invention relates to pipe-hangers, and particularly to that class ofhangers which is provided with an adjustable clamp, enabling the hangerto be accommodated to su pportingbeams of varying widths, and, further,which is verticallyadjustable toenable the pipe to be supported atdifferent heights, such vertical adjustment being secured withoutdisconf necting the pipe from the hanger.

Furthermore, our improved hanger provides means for securing the pipe ina plane, cutting the plane of the supporting-clamp at any desired angle.

Said invention consists of means hereinafter fully described, andspecifically pointed out in the claims.

The annexed drawings and the following description set forth in detailcertain mechanism embodying the inventiongch disclosed meansconstituting but one of various mechanical forms in which the principleof the invention may be used.

In the annexed drawings, Figure l represents afront view of our improvedhanger supported by. a suitable I-beam, shown in broken section andholding a pipe, also shown in section. Fig. 2 represents a partial sideelevation and a partial vertical section of the device asillustrated inFig. 1. Fig. 3 represents a horizontal section of the clamp forming apart of our invention, and Fig. 4 shows in perspective one of thecomponent sections of said clamp.

Referring to the drawings, A represents a section of an I-beam, rail,girder, or other suitable means of support. A clamp B is adapted toengage said support and comprises two similar sections I) b, adapted tobe adjustable in a horizontal plane, so as to accommodate said clamp tobeams of varying widths. Said horizontal adjustability is obtained asfollows: Each section comprises an arm and an end piece Z22, said armbeing' connected to said as shown in Figs. 3 and'lf, and at aboutonethird of the distance from the other edge of said end piece b2 isprovided a slot 3 of substan tially the same height and width as an armand through which the arm of the other section I) is adapted to bepassed, as shown in Figs. 1 and 3, and in which it is adapted to besupported, whereby the sectionsb can be adjusted relatively to eachother to enable the clamp B to engage beams of varying widths, suitablehooks b4 being provided on the end pieces b2 to grip over the flanges at of the beam A. The sections t having been adjusted as is desired maybe fastened securely rela tively to each other by means of a suitablescrew 55 and a plurality of suitably-alined screw-holes 5G.

rIhe screw b5 is adapted not only to retain the sections b Z) securelyrelatively to each other. butalso forms a support for a hangerrod O,which is connected to the clamp B by means of a suitable cap c, throughwhich is passed and against the under edge of which abuts a swivel-jointc/adapted at its outer end to pass between the arms b' b of the sec'-tions b Z) and provided with a suitable screwhole registering with thescrew-holes L of the arms H. The lower end of the hangerrod Ois providedwith the construction clearly shown in Fig. 2, comprising theinteriorlythreaded sleeve D, adapted at its upper end to engage thelower threaded end of the hangerrod O and at its lower end to engage theeX- teriorly-threaded member E, provided with a jam-nut e, adapted toscrew up tight against the under surface of the sleeve D. It will benoted that by loosening up the nut e the construction shown anddescribed enables the raising or lowering of the member E withoutdismantling or disconnecting any parts of the device by simply turningthe hanger-rod O in the proper direction. The member E is adapted toreceive and retain the two ears ff of a pipe-supporting' band F, adaptedto encircle and hold up a pipe G or any other object which it is desiredto support.

In case it is desired to support a plurality of pipes G from one clamp Bsome of the hanger-rods O may be secured to said clamp laterally of thecentral vertical plane passing through the beam A and either inside ofor outside of the end pieces b2.

It will be noted that the said construction gives a wide latitude to thewidths of supporting-beams with which it may be readily and effectivelyconnected and that after the connection with the pipe is made andsecured the latter may be rotatedthrough any arc and into a position atany desired angle relatively to the supporting-clamp and also adjustedvertically within the limits of movement of the member E within thesleeve D without disconnecting the beam or pipe from thehanger or any ofthe constituent parts of the latter from the other parts of the same.

Other modes of applying the principle of our invention may be employedinstead ofthe one explained, change being made as regards the meansherein disclosed,` provided the means stated by any one of the followingclaims or the equivalent of such stated means be employed.

We therefore particularly point out and distinctly claim as ourinvention- 1. ln a pipe-hanger, a clamp comprising two sections, eachsection comprising an arm and beam-engaging means and provided with aslot in which the arm of the other section is adjustable; and means forfastening said sections together in any desired position.

2. In a pipe-hanger, ay clamp comprising two sections7 each sectioncomprising an arm and a supporting member adapted to engage a beam andprovided with a `slot in which the arm of the other section isadjustable, whereby the distance between the supporting members may bevaried; and means for fastening said sections together in any desiredposition.

3. In a pipe-hanger, a clamp comprising two similar sections, eachsection comprising an arm and a supporting member adapted to engage abeam and provided with a slot in which the arm of the other section isadjustably mounted` whereby the distance between the supporting membersof the two sections may be varied; and means for fastening said sectionstogether in any desired position.

Signed by us this 21st day of July, 1904.
